Your car is equipped with a central locking system.
The central locking system allows you to lock and unlock all doors, the fuel fill-
er flap and the boot lid at the same time.
Depending on the equipment configuration, the following applies after
unlocking
› The turn signal lights flash twice as confirmation that the vehicle has been
unlocked.
› The doors, the boot lid and the fuel filler flap are unlocked.
› The interior light operated via the door contact illuminates.
› The SafeLock system is switched off.
› The indicator light in the driver door stops flashing.
› The exterior mirrors are folded back into the driving position.
› The anti-theft alarm system is deactivated.
If the vehicle is unlocked and a door or the boot lid not opened within the next
45 seconds, the vehicle will lock again automatically and the safe securing sys-
tem or anti-theft alarm system will be switched back on. This function is inten-
ded to prevent the car being unlocked unintentionally.
The seat and mirror are adjusted after the vehicle is unlocked » page 89.
Depending on the equipment configuration, the following applies after
locking
› The turn signal lights flash once as confirmation that the vehicle has been
locked.
› The doors, the boot lid and the fuel filler flap are locked.
› The interior light operated via the door contact goes out.
› The SafeLock system is switched on.
› The warning light in the driver door begins flashing.
› The exterior mirrors are folded back into the park position.
› The anti-theft alarm system is activated.
If the doors or the luggage compartment lid remain open after the vehicle has
been locked, the turn signal lights do not flash until they have been closed.
The current position of the seat and mirror after the vehicle is
locked » page 89 .WARNING■
Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!■
When leaving the vehicle, never leave persons who are not completely in-
dependent, such as children, unattended in the vehicle. The children might,
for example, release the handbrake or take the vehicle out of gear. The ve-
hicle could then start to move – risk of injury and accidents! These individu-
als might also not be able to leave the vehicle on their own or to help
themselves. Can be fatal at very high or very low temperatures!
CAUTION
■ Each key contains electronic components; therefore it must be protected
against moisture and severe shocks.■
Keep the groove of the keys absolutely clean. Impurities (textile fibres, dust,
etc.) have a negative effect on the functionality of the locking cylinder and ig-
nition lock.
■
The battery must be replaced if the central locking or anti-theft alarm system
does react to the remote control at less than approx. 3 metres
away » page 224 .
■
When leaving the vehicle, always check if it is locked.
■
If the driver's door has been opened, the vehicle cannot be locked.
54Using the system
Pressing once switches the seat heating on at its maximum level.
With repeated pressing of the switch, the intensity of the heating is reduced
until it is switched off.
The level of the seat heating is indicated by the number of illuminated warning
lights underneath/in the switch.
If the engine is switched off and then turned on again within 10 mins with the
driver seat heating switched, then the driver's seat heating is automatically
turned on again.WARNINGIf, as a passenger, you have a subdued pain and/or temperature sensitivity,
e.g. through medication, paralysis or because of chronic illness (e.g. diabe-
tes), we recommend you do not use seat heating on the driver's or front
passenger seat. This can lead to burns on the back, the posterior and the
legs which are difficult to heal. If the seat heating is used, we recommend
to make regular breaks in your journey when driving long distances, so that
the body can recuperate from the stress of the journey. Please consult your
doctor, who can evaluate your specific condition.
CAUTION
■ Do not kneel on the seats or otherwise apply concentrated pressure to them.■The seat heating in the following cases will not turn on - there is a risk of
damaging the seat covers and seat heating. ■The seats are not occupied by people.
■ Items are fastened or stored items on the seats, such as a child seat, a bag
and the like.
■ Additional seat covers or protective covers are fixed to the seats.■
Clean the seat covers » page 187.
